Title: A method of controlling a communications link
Inventor: BAINES STEVEN JOHN
IPC: H04L1/06
Filed: 2003-08-05
Abstract: The present invention is directed to a method of controlling a communications link and apparatus configured to perform this method. This invention is particularly related to but in no way limited to MIMO (multiple inputs multiple outputs) wireless communications systems. The method comprises the steps of determining at the receiver the quality of the communications link and based on this, selecting a group of transmission parameters and an element from this group.  These selections are then communicated to the transmitter. The transmission parameter may be the transmission configuration such as the modulation and coding scheme. The invention minimises the required feedback signalling from the receiver to the transmitter by exploiting temporal correlation of the parameter being controlled, whilst allowing rapid selection of the parameter.
